Hello, we are starting a new online service targeted to people that need to boost the number of their email subscribers. We are looking for a PPC advertising network focused on the US market that is working well in the digital marketing niche. I've found a big number of networks here: https://forums.digitalpoint.com/threads/any-fast-ppc-campaigns-other-than-google.2655791/ but I'm lloking for an advice which of them (or some other) works fine for digital marketing services. Adwords is not an option, because the bids for our niche start at $20.00 Thanks !
We have served 17,284,000,000 banner impressions in the US in the past 30 days. I would think some of these impressions would suit your target(s)
